2.4 Flower Survey
The flower survey was carried out in the spring and autumn season during the pollinator survey in the same transect. We made five quadrates of 10 m X 5 m in each sampling transect. For estimation of flower resource abundance, we scanned insect pollinating herbs and shrubs in each quadrate and identified genus and species levels. The cover of floral resources in each quadrate was ranked between 1– 6 (Szigeti et al., 2016). Rank 1 indicates very scarce, 2 for scarce, 3 for more or less scarce, 4 for more or less abundance, 5 for abundance, and 6 indicates extremely abundance. The flower resource abundance for each sampling transect was calculated as FLOWER=\(\sum_{i=1}^{n}\text{t.taxon}_{i}\ (\ t\ =mean\ of\ the\ rank\ of\ flowering\ plant\ of\ each\ transect).\backslash n\)2.5 Identification of Insect Pollinators
All the insect pollinators were identified to species level in the laboratory using relevant keys from adjacent regions.
